DIY VS GWIN — SAME PRICE. NOT THE SAME RESULT.
You're probably comparing DIY systems right now…
They all look similar. They all claim savings. But here's what actually happens:
THE PROBLEM WITH DIY HVAC
- Most Techs Will Not Touch It After installing a DIY system, it's hard to find a qualified tech willing to service it. Often, you're left stranded when problems arise.
- Hidden Leaks Go Undetected Without a professional vacuum test, refrigerant leaks go unnoticed for months — until your system fails completely.
- Your Warranty Vanishes Most DIY warranties are impossible to claim without professional documentation. You’re at risk if anything goes wrong.
- Heating struggles below -13°F If a leak occurs, refrigerant is lost, and the homeowner is responsible for repair, replacement, and service costs- if you can find tech to fix it.
GWIN "ASSISTED DIY" SOLVES THEM ALL
- GWIN Comes With a Tech A certified GWIN tech inspects, vacuums, and charges your system.
- Zero-Leak Certified Professional vacuum test catches every leak before it becomes a problem. Verified and logged.
